T 0 all whom "it may concern:

Be it known that we, WrrnLocir HUBBELL and CARL Lnsnrn HILTON, citizens of the United States, and residents of Wilton, in

the county of McLean and State of North Dakota, have invented a new and useful Improvement in Gang-Plows, of which the followingis a full, clear, and. exact description. Q

The purpose of the invention is to rovide a gang'plow which in operation w'l clear itself from stones or sirnilarobstacles, and

the plow beams whereof are free to autornatically rise and fall their full length, or independently at the front or at the rear, as

' occasion may demand, which beams are also lozenge shape,

Fig. 1. I the front bar 10,1and is also pr of channel iron, together with capable of lateral movement, being springcontrolled in all directions of their 1novements.

' Another urpose of the invention is to provide a sinip e and effective means for simultaneously raising and lowering all of the .plows of the gang, and to provideacolter for each plow that travels aheadoi its point adjacent thereto, extending down below the lower line of the point, whereby when a colter rolls over an obstruction itcarries the plow point with the same.

The invention consists inthe novel construction and combination of the several parts as will be hereinafter fully set forth and pointed out'in the claims.

' Reference is to he had to the accompany-1 ing drawings forming a partoi' this specification'in which. similar characters of refer- .ence indicate corresponding parts in all the figures.

Figure 1 is a plan View of the improved plow; Fig. 2 is a section taken practically on the line 2-2 of Fig. 1; Fig. .3 longitudinal section through a portion of the machine, drawn upon an enlarged scale,

is a detail.

illustrating the right-hand plow beam, and

the-manner in which a colter raises a plow point when riding ver an obstruction; and Fig. 4 is-a plan view of the parts shown. in Fig; 3. n The frame of the machine is substantially comprising a front bar 1.0, preferably in the form of a channel iron, which front bar is to the'line of draft of the machine as" .is illustrated by the arrow in parallel with .y made two side bars Hand 13, that are diagonally located with A rear bar 11, which is :3.

channel brackets 15 and said frame. These plow beams are in gangs and a gang may comprise two or more beams, preferably five being employed in connection with one frame. These plow beams A are arall'el with the-side bars 12 and 13 of the frame, and. each beam A at its rear end carries a plow share 16 of any approved type. The beams A at their forward ends are made to enter between the upper and lower members of channel brackets 15, preferably of triangular shape in plan view, which brackets 15 are secured to the outer faces of the front bar 16, as is best SlIbWI l L 3.

A pin 1'? is pessedthroiig each through a suitable opening in the forward end of the beam and in the opening of the beam through which thepin 17 is passed, a friction roller 18 is located, having bearing against as is. also bestshown in Fig. 3, and a spring 'ing said pins.

An arch 20 is sprung across the frame adjacent its rear bar 11, which arch is parallel with said rear haranii extends frornone side bar to the other, as is best shown in Fig. 1, and said "ch is'su-p ortsd or braced by suit able ,icds or bars 21 that are-attached to the arch and to the forward. har 'lii of the frame. A i-standard 22 is secured any suitable'or approved manner to each of the plow beams A adjacent where the said beams are curved at'their rearends, and the said standards 22 pass up through openings in the arch 2O having free movement in said openings, and the u .per ends with nuts 23, or theii' equivalents.

plow beams in a vertical direction, and the the pin,

iilow shares are held ins suitable position to ater l 1. around the said standards 22, havbe ring at their upper ends against the under laces of the arch 20, and at their lower ne ground by means of springs 24 that 'i-flends upon a nut 25, said nut being located'at the lower portions of the said-'j's tandards whereby to increase or decrease the-tension ofthe springs 24. d

Friction rollers 26 are made to engage preferably'with right-handfacesof the plow beams A at heir rear portions and the said rollers 26 ,are mounted in brackets 27' that are secured to the rear bar 11 of the 'frafne' with theexception iofthe bracket for the roller'that engages the right-hand bar, which latter bracket,- designated as 27 is secured to the right ha'nd side bar 12 of the frame, and a spring28 is'provided' for each of the said bars, .whichsprings are attached to the beams adjacent their-rear ends and all of the springs with the exception of the right hand one, are secured to'the' rear .bar 11. of the frame, the ri ht-hand s ring being at;

tached to the rig t-hand-sire bar 12, as is shown in Figs. 3 and 4. These springs 28 serve to hold the beams against therollers'26 and likewise admit of the beams and their plows moving sidewise .-'or laterally should they meet'an obstruction, returning the said .beams to their normal position after the ob- 'struction is passed, while the springs 24 on the standards 22 admit of the rear end ortions ofthe plow beams being raiser "to mount an obstruction returning the beams I to their normal position after the obstruction is passed, and the forward springs 19 admit of upward movement of the beams at their forward ends and return-the said beams to their normal position. forward when the springs are relieved from tension.

Adjacentthe forward end of each beam A, a hanger .29 is securedi the said beam extending down therefrom, and in each hanger 29, a rolling colter 30 is mounted to revolve.

' These colters are opposite the points of the shares 16, and are quiteclose to said points and extend down below. the points so that when a colter travels over a stonejor other obstruction, as is shown inl ig. 3, the share 1 carried bythe beam with which the colter struction.

is connected is liftedwell; up from such ob A brace 31 is provided for each of the colters-30, and these braces serve as shoes-and are s'ecuredto the beams A be tween the hangers 29, and the forward ends of said beams, and are carried down from the": beams and are then curved .hp'wardly and rearwardly and theirrear ends are bifurcated and carried sufficiently far to the rear to receive the trunnions of the colters 30 after theyhave passed through the'hangers 29.

-Theseishoes 31 serve to prevent the plows from going too deep when traveling over a' mound or ridge lengthwise thereof.

.' tubular standard32 is secured to the ,rear

auxiliary bracket 14, as is best shown in;

Figl2, and a brace 33' extends from't he'upper portio of the s'aid tubular-stanldard, to the, 'JsQd; Farah 20. A spindle 34-is mounted to in the tubular standard 32, extending above and below said standard, and at the bottom end of the s indie 34 a horizontal "bearin 35 is provide for the roller ,At t eforward ortion of the frame, adja cent each end 0 the front barlO thereof,

brackets 37 ,are firmly attached, and each of the said brackets has attached thereto an upwardly extending tubular standard 38 corresponding tothe tubular standard 32 heretofore referred to, and. in each tubular standard 38, a spindle 39 is mounted to slide, extending also above and below the said standard 38, and rearwardly extending arms 40 area--- secured to the upper ends of the spindles 39, and a connecting rod 41 is attached to thesechains are carried down and are secured to and are adapted to be wound around a shaft 43 that is journaled in suitable bearings located upon the upper face of thefront bar 10 of the frame, as is illustrated in Figs. 1 and 2. p

A third chain. 44 is likewise secured to the shaft 43, usually at its left-hand end portion, and this chain 44 is carried rearward and passed beneath and in engagement with a 'groovedroller 45 mounted in suitable bear ings 46 secured to the centralrportion of the rear bar member. 11 of the frame, as is illustrated in Fig. 2, and the said chain 44 is carried oversaid roller 45 to an arm 47 located at the upper end. of the rear spindle 34, each chain being attached to said. arm, as is also shown in Big. 2; Thus by turning-the shaft 43 in one or the ,other direction the frame in its entiret and the parts carried thereby are raised an lowered so that the plows may enter the ground to a greater or lesser degree,"

.or be" carried sufiiciently far above the sur face to permit the nachineto be readily transported from place to place. It is-also the beams- Aare capable of upward move-1 ment at'their ends throughout their len th, and" that they are likewise all capableof atera'lmovementfa'nd are spring-controlled in both movements. .Therefore when a plowshare has cleared an obstruction whether by ridin over it or by sliding by its side, after the ,o struct'ion is passed the beam in action is returned to its normal position. '9

A draft bar 48 is connected b suitable links 49 to the front bar 10 of the rams, and this draft bar is provided with a clevis 50 whereby to connect the machine with a traction engine or other type of motor, and it evident from the" foregoing description that Y may be here. remarked that the left-hand end portion of the shaft 43 is rendered polygonaland isreduced, as is shown at 51 in F 1g. 1.

. At' the right-hand end of the shaft 43, a

' the said tumbling rod is provided with a orank disk 57, whereby tIYTnake suitable connections' with a driving mechanism of the ensuch'ian event the draft bar 4-8 isn ade to I extend the full length of the. front portion of ward tension on said nected with the frame and the beam exert- Fig.' 1.

worm".wheeli52 is secured, .and this worm wheel engages with theworm, not shown, but

which'is carried by'a shaft 53 mounted,

transversely upon the right-hand end portion of the forward frame member, as is shown in knuckle joint 64 with a member 55 with a tumbling rod that leads to the engine, and

j the other member56of the said tumbling rod Bturns with the member 55 and slides there- I spring.-

on, and the outer 'or telescopic member 56 of ine=or motor, and a standard-58 is provided or the tumbling rod,bein% loosely mounted thereon, adapted to have caring on a platform or a suitable support on the engine.

- The frame is braced by'means of a trans verse rod-59 that extends from the left-hand front portion of the frame to theright-hand rear portion, as is shown in Fig; 1, so that he frame is rendered exeeedinglf stiff, and is capable of standing hard. usage. The

left-hand add the shaft 43 is squared, or

made polygonal order'to receive one end of a sultable" coupling when two gangs of plows are tobeoperated together, and in the frames of both gangs.

' Having thus described our invention, we claim new and desire to secure by Letters Patent,- i Y 1.
